FOREWORD TO VOLUME I 



These proceedings result from the first symposium held by Project 

 II-1.3 of the Joint US-USSR Committee on Cooperation in the field of 

 Environmental Protection, established in May 1972. 



Broad review papers were included in the symposium in order to 

 acquaint scientists from each country with the water pollution perspective 

 upon which current programs are based. There are differences and therein 

 lies the value of meeting together.
